The KingRoot one click root app is available to download for devices running Android 4.2.1 Jelly Bean. Once you install the KingRoot Android 4.2.1 Jelly Bean APK, you will have three new apps available from your device’s app drawer. You will have one under the same name (KingRoot) and two others: King User and King Master. The King User is the app you want to access if you want to unroot the device. You will see what to do once you enter the app for that. The KingUser is also useful for remove system apps and disabling the auto-start of apps. King Master improves the device performance by archiving notification and making app hibernation automatic.

Once you understand how the KingRoot rooting tool works, it’s easy to use. Just browse the list of supported devices from the list below and the app will work for all Android software version that is currently being used. It works for the popular Android KitKat, Android Jelly Bean, Android Lollipop, Android Ice Cream Sandwich and Android Gingerbread. Only roughly 0.4% of Android devices are currently running Android Froyo. If you are one of those devices, the KingRoot universal one click rooting tool works for them too.


Arguably the best part about the KingRoot app is that it is near impossible to brick your device when you use the tool. With an average rooting guide, you must at least apply the steps and see if it works. It’s a big risk since it might not work and brick your device. With the KingRoot app, you just click the button, and it checks to see if your device can be rooted first. If the answer is no, then you can just delete the app and not use it. If the answer is yes, then you can proceed and open the system internal with the root access you always wanted to have on your device.

While the KingRoot one click rooting APK is easy to use, it’s still granting access to the root file system. Whenever you have access to the root file system, you are leaving your device vulnerable. The two main reasons for the vulnerability include the fact that you can delete necessary files from the file system, and you exit the device more open to potential malware attacks if you download a bad file. So, now that you know that, you should backup your data before starting the guide. As long as you do backup the device, you should have no worries restoring that data again later, no matter what you delete by accident.

Now you can exit the app and start installing all of those awesome apps from the Google Play Store that require root access. Furthermore, nothing is stopping you from installing a custom recovery and installing a custom ROM if you like. You can start by installing the root checker app just to make sure your device really does have root access.

It does not matter if you flashed SuperSU from a custom recovery like TWRP and ClockworkMod or installed a one-click rooting tool like KingRoot and VRoot, they both mean you are now the root user and have full privileged control over the Android operating system. Having root access allows you to install any apps that you want to install. That means you have free range over the thousands of additional apps called root apps that would not run on your system up until now. You probably know many of these names already: Titanium Backup, Tasker, Greenify, ROM Manager, Viper4Android and so forth. It is up to you what is installed and up to you how your device now runs. If you want a better music experience, then you want to install Viper4Android. If you did not like any of the backup apps that were available before today, then Titanium Backup is what you want to install. If you think you want to be more like Data from The Goonies and that you have some feature ideas that were not included in the stock version of Android then Tasker is the app to try. The Google Play Store is riddled with these root apps that do nothing but help you create the device you want to have.

One thing you need to be wary of though is the fact that Google Play does not show you a list of what the root apps are and the root apps that are trending like it does with the stock apps. You need to open the Google Play Store app with the knowledge or already knowing the names of the root apps that you want to install. We are here to help you with this. All you need to do is check out our list that includes some of the best root apps for the Android operating system to be found in the world and then writes down the names, so you do not forget them.
